Description of intervention(s) / exposure
The aim of this project is to design and 3D print a stoma guard that is tailored to a patient's individual abdominal wall and stomal measurements, with the goal of improving their quality of life, reducing pain, and lowering the requirement of surgical parastomal hernia repair.
We will take detailed measurements of each patient's waist, abdominal wall and stoma to create a customised stoma guard design. We estimate this will take 45 minutes to complete, and will be undertaken by a medical student and research fellow working on this project. With these measurements, we will print using polylactic acid polymers and fit the customized stoma guards to the patients, ensuring proper comfort and functionality.
Patients will wear the guards for four weeks, and be encouraged to wear the guard while not sleeping/bathing, or emptying the stoma bag. Participants will be asked to clean the guard between each emptying of the bag with 70% alcohol wipes, which will be provided. A member of the research team will contact the participants each week to monitor use and receive feedback regarding the device.

This is a pilot study in which the primary objective is to determine the feasibility and process for developing a tailored hernia guard. As such, we will recruit a convenience sample of 15 participants. This will also allow us to address the secondary objective of identifying themes of the patient experience with the parastomal hernia halt is expected to enable us to reach saturation of themes and breadth (meaning of messages).

Patient demographics will be described using appropriate descriptive statistics (mean and standard deviation for normally distributed continuous variables, median and inter-quartile range for other continuous variables, count and percentage for categorical variables).

Qualitative data will be summarized into themes. This is a novel qualitative study exploring patient perceptions of this device. For comparison of categorical data the Chi-square test or Fischer’s exact test will be used where appropriate. Continuous data, such as before and after SF-36 and pain VAS scores will be analysed using the independent samples t-test (reporting mean and standard deviation) and Wilcoxon Rank Sum (reporting median and interquartile range) test for normally and non-normally distributed data, respectively. The Shapiro-Wilk test will be used to assess the distribution of the data.

Summary
Brief summary
Parastomal hernias are common complications following bowel cancer surgery with the formation of a stoma. These occur when abdominal contents protrude through the abdominal wall at the stoma site. Hernia symptoms can include pain, bulging, leakage, skin irritation, difficulty fitting the stoma, and occasionally life-threatening complications. The main treatment is surgical repair – but unfortunately the rate of hernia recurrence is high. Stoma guards and supportive devices can provide support to the abdominal wall around the stoma site, reducing symptoms associated with hernias, and possibly the need for surgery. The aim of this project is to 3D print a tailored stomal guard to improve quality of life, reduce pain, and the risk of surgical intervention.
